Megger’s MTO106 transformer ohmmeter is designed for safe, accurate field measurement of winding resistance in smaller transmission and distribution transformers. It has dual channels with a measurement range and accuracy suited to provide information about the majority of power transformers, reactors and instrument transformers.

Megger’s DLRO2 low-resistance ohmmeter tests the resistance of inductive loads at 1A. It is designed for outdoor use with protection against dust and moisture. The difference meter enables repetitive measurements to be compared with an initial reference measurement. It translates the percentage difference to a needle and pointer movement, making the changes clear to see.

Megger’s 200A battery-powered micro-ohmmeter is designed to measure the resistance of circuit-breaker contacts, bus-bar joints and other high-current links. It can can deliver a high current during the discharge and can store a large amount of energy compared to conventional capacitors.
